25 Most Endangered Primates
Written by: Admin
The primates play an important role in the ecology. The primates are also important to study human development as they are considered the closest living relatives of mankind. Although many organizations around the world are working to protect primates, the decreasing population of primates is concerning. According to the IUCN Species Programme report (Primates in Peril: The World’s 25 Most Endangered Primates, 2008–2010), almost half of the all primates are in danger of becoming extinct if appropriate actions are not taken immediately. The causes of primates extinction include; destruction of tropical forests, illegal wildlife trade, and commercial bush meat hunting.
Dr Christoph Schwitzer, advisor to the IUCN SSC Primate Specialist Group and Head of Research at the Bristol Conservation and Science Foundation said, “This report makes for very alarming reading and it underlines the extent of the danger facing many of the world’s primates”.

“The purpose of our Top 25 list is to highlight those that are most at risk, to attract the attention of the public, to stimulate national governments to do more, and especially to find the resources to implement desperately-needed conservation measures. We want governments to commit to these measures when they gather in Japan in October. We have the resources to address this crisis, but so far, we have failed to act.” says Dr Russell Mittermeier, Chair of the IUCN SSC Primate Specialist Group and President of Conservation International.
